Our Parishes


The Patronage of St. Joseph Parish

Established 1869

264 Washington St, Somerville, MA

St. Joseph Parish has the distinction of being the first Roman Catholic Parish established in the city of Somerville. The church is High Victorian Gothic in style and is located in Union Square. The architect was James Murphy.  The church was built in 1871 and dedicated in 1874. The first Pastor, Rev. Christopher McGrath was appointed in 1869, later becoming a monsignor. He served as Pastor of St. Joseph’s for 63 years. A section of Route 28 is named in his honor

The church today still holds a commanding presence in the square. While the planned redevelopment of the square will transform the area the parishioners of St. Joseph continue to transform souls through the Holy Sacrifice of the Mass and service opportunities. The Parish is made up of a very dedicated and faithful group of parishioners who make everyone feel at home as soon as they walk through the doors. Please stop by and introduce yourself.


St. Ann Parish

Established 1881

50 Thurston St, Somerville, MA

St. Ann Parish was the second Catholic parish to be established in Somerville. With the steady influx of immigrants settling in the Winter Hill area in the late 1800’s Monsignor McGrath saw the need for a new parish and St. Ann was established in 1881. The first church was a wooden structure that served the parish well for many years and was later used as a parish hall. The current church was built in 1897 and dedicated in 1906, being Romanesque Revival in style it is a beautiful place to worship. The architect was Thomas Francis Houghton.

Parishioners refer to themselves as St. Ann Parish Family because everyone is welcome and made to feel at home. The Parish is diverse and embraces many nationalities. Masses are offered in English and Haitian Creole. The life of the parish is centered on the Eucharist and Holy Sacrifice of the Mass. We have a vibrant faithful Haitian community and a Spanish charismatic community with many apostolates. Parishioners are actively engaged in many ministries and volunteer programs. Please come and say hello.


St. Catherine of Genoa Parish

Established 1891

179 Summer St, Somerville, MA

St. Catherine of Genoa Parish is located in the Spring Hill area of the city. The church was constructed between 1907 and 1920 and designed with the belief that the building should connect American immigrant Catholic aesthetic and spiritual experience.  Much of the interior is done in blended marble imported from Carrara, Italy. The architect was Charles D. Maginnis of Maginnis, Walsh and Sullivan.  St. Catherine has been called the “gem of the Boston Archdiocese” because of its breathtaking beauty.

Today St. Catherine’s is a vibrant, active parish with many young families who also attend our school. We have a wonderful Christmas bazaar, and other parish sponsored activities throughout the year. The music program is outstanding, but most importantly, St. Catherine’s is a warm, friendly, and supportive place, with wonderful and dedicated parishioners. St. Catherine has a delightful and dedicated accredited elementary school. The School welcomes children from preschool to grade eight. St. Catherine of Genoa Elementary School is situated close to Cambridge and Boston, which makes it a very easy commute for parents between job and school.

Tri-Parish Catholic Community and Collaborative

Starting in 2007 St. Joseph’s, St. Ann’s, and St. Catherine’s started working together as a Tri-Parish Community in response to the New Evangelization.  With implementing the Disciples In Mission program we draw on the strengths of each parish and help each other in our weaknesses giving us the opportunity to better serve one another and all the children of God. The Collaborative was officially started on July 1st 2015 and is currently working together to build Christ-centered relationships and fearlessly spread the Word of God, bringing others closer to Christ and truly going forward to “make disciples of all nations”.
